@riginal application led February 23,1909, Serial No. 479,316. Divided and this Iapplication lef July 2, 19091. Serial No. 505,720.

.To all 'whom it may concern:

Be it known that I, JAA/ins JOSHUA MID- onnnooir, a subJect of the King' of Great Britain, residing at Sault Ste. Marie, county A c .i of (Jhippewa, and btate of Michigan, have invented certain new and useful ltmprovements in llfotor-Plows, of which the following is a specification.

This lnvention relates to plows.

rlhe present inventiolnwhich is a division of my copending application, Serial No. 479,316, filed Feb. 28, 1909, has for its object the provision of novel means for supporting a plow and adjusting it in relation to the wheeled carrying vehicle therefor, being especially designed for use as a motor plow, propelled by `suitable mechanism, preferably that set forth in my aforesaid earlier filed application.

The invention is carrie-d out by the provision of novel means whereby the plow may be raised and lowered in relation to the Y motor plowV frame and whereby it may swing or move laterally as will appear more fully hereinafter. y

In the accompanying drawings -fFigure 1 is a side elevation, the driving mechanism for the motor plow being omitted; Fig. 2, a plan view showing' so much of the plow frame as will enable the invention to be fully understood; and Fig. 3, a perspective detail of the adjusting and supporting devices.

The frame 1 of the machine has a steering wheel 2 and traction wheels 13 and 17 of any preferred form and arrangement and may carry any snitablemotor f or propelling it as, for instance, a gasolene tank 29 and gasolene engine 30. v

The plow has its beam 51 connected by a clevis 52 to a rocker 53 depending from frame l, which permits the plow to properly operate. Secured to the rear end or the plow is a link 511- to the upper end of which is attached a slide `55 whichis adapted to slip laterally on an arc-shaped guide 56, which is provided with vertical guides 57 slidable in guide-ways 58 inthe frame l. Articulated connections 59 connect tho guides 57 with a rocker 60, which is adapted to be operated by a lever 61. This construe tion permits elevation of the rear 'end of the plow as may be desired so that it will be adapted to out as deep a furrow as desired, while the plow is laterally at its rear part, an hence all inequalities of the ground being plowed are compensated for and the plow automatically adapts itself to the direction of travel of the machine.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, isi 4 In a plow, the combination with a wheeled frame having vertically disposed guideways, of a transversely disposed-arc-sllaped guide dislposed below the frame aforesaid, vertical y dis nosed guides secured to said transversely isposed guide and slidable in the guideways, a plow having a beam pivoted to the frame, a slide to which theplow is secured which is slidable on said transversely disposed guide so thatt it can swin sidew1se of the frame, and, raising an lowering mechanism. directly coperating 'with the vertically disposed guides for raising and lowering them.

In testimony whereof, I hereunto affix my signature 1n presence of two witnesses.

JAMES JOSHUA MIDDLEBROOK.
